A kind of micro-porous permeable material is prepared based on common features of existing permeable materials and taking dense accumulation of fine sand as the matrix and epoxy resin as binder.

Polymer microporous materials have a structure highly regularized, with open spongy porous structure interweaving each other, and the pore size can be tailored as desired.

Application of supercritical CO_2 in preparation of microcellular plastics in continuous extrusion;

The conception, foaming principle, phylogeny and four preparation method including thermally induced phase separation, monomer polymerization reaction, gas supersaturation and precipitation with a compressed fluid antisolvent of microcellular plastic were summarized.

The application of supercritical CO_2 in extrusion process was discussed respectively according to de- crease the polymer melt viscosity and as a foam agent for prepare the microcellular plastic.
